Set up your email accounts on every Apple device without retyping passwords.
Mailpack is a Mac app. Enter your IMAP accounts once. It saves them in one encrypted file and installs them in Apple Mail on your Mac and iPhone, or writes a Thunderbird setup file.
How it works
- Add each account once: address, username, password or app password, and the IMAP and SMTP servers.
- Save an encrypted .emailpacket file as your backup. It is locked with a passphrase you choose.
- Install on this Mac in one click, or save a profile and AirDrop it to your iPhone.
- Optional: save a Thunderbird file that creates the same accounts in a new Thunderbird profile.
What it supports
| Target | Result |
|---|---|
| Apple Mail on Mac | Account installed, password included |
| Apple Mail on iPhone and iPad | Account installed, password included |
| Thunderbird | Accounts created. Thunderbird asks for each password once. |
| Outlook, Gmail app, Spark and others | Not supported. These apps cannot import accounts. |
Security
- The .emailpacket file is encrypted with AES-256-GCM. The key comes from your passphrase using PBKDF2-HMAC-SHA256 with 600,000 iterations.
- Nothing is uploaded. Mailpack has no account, no server and no tracking. Everything stays on your Mac.
- The iPhone and Mac profile files contain passwords in plain text. Delete them after installing.
- Two-factor secrets are never stored. Use an app password for accounts with 2FA.
Limits
- Gmail, Outlook and iCloud accounts that use browser sign-in cannot be moved. Each app needs its own one-time approval.
- Android is not supported yet.
- Profiles are unsigned, so macOS and iOS show a "Not Signed" notice when you install.
